The DIGEST-MD5 SASL mechanism is used to perform all processing related to SASL DIGEST-MD5 authentication.
The DIGEST-MD5 SASL mechanism is very similar to the CRAM-MD5 mechanism in that it allows for password-based authentication without exposing the password in the clear (although it does require that both the client and the server have access to the clear-text password). Like the CRAM-MD5 mechanism, it uses data that is randomly generated by the server to make it resistant to replay attacks, but it also includes randomly-generated data from the client, which makes it also resistant to problems resulting from weak server-side random number generation.
The Digest MD5 SASL Mechanism Handler component inherits from the SASL Mechanism Handler
The following components have a direct AGGREGATION relation FROM Digest MD5 SASL Mechanism Handlers :
A description of each property follows.
| Basic Properties: | Advanced Properties: |
|---|---|
| ↓ enabled | ↓ java-class |
| ↓ identity-mapper | |
| ↓ quality-of-protection | |
| ↓ realm | |
| ↓ server-fqdn |
| Description | Indicates whether the SASL mechanism handler is enabled for use. |
| Default Value | None |
| Allowed Values | true false |
| Multi-valued | No |
| Required | Yes |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | No |
| Description | Specifies the name of the identity mapper that is to be used with this SASL mechanism handler to match the authentication or authorization ID included in the SASL bind request to the corresponding user in the directory. |
| Default Value | None |
| Allowed Values | The DN of any Identity Mapper. The referenced identity mapper must be enabled when the Digest MD5 SASL Mechanism Handler is enabled. |
| Multi-valued | No |
| Required | Yes |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | No |
| Description | The name of a property that specifies the quality of protection the server will support. |
| Default Value | none |
| Allowed Values | confidentiality - Quality of protection equals authentication with integrity and confidentiality protection. integrity - Quality of protection equals authentication with integrity protection. none - QOP equals authentication only. |
| Multi-valued | No |
| Required | No |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | No |
| Description | Specifies the realms that is to be used by the server for DIGEST-MD5 authentication. If this value is not provided, then the server defaults to use the fully qualified hostname of the machine. |
| Default Value | If this value is not provided, then the server defaults to use the fully qualified hostname of the machine. |
| Allowed Values | Any realm string that does not contain a comma. |
| Multi-valued | No |
| Required | No |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | No |
| Description | Specifies the DNS-resolvable fully-qualified domain name for the server that is used when validating the digest-uri parameter during the authentication process. If this configuration attribute is present, then the server expects that clients use a digest-uri equal to "ldap/" followed by the value of this attribute. For example, if the attribute has a value of "directory.example.com", then the server expects clients to use a digest-uri of "ldap/directory.example.com". If no value is provided, then the server does not attempt to validate the digest-uri provided by the client and accepts any value. |
| Default Value | The server attempts to determine the fully-qualified domain name dynamically. |
| Allowed Values | The fully-qualified address that is expected for clients to use when connecting to the server and authenticating via DIGEST-MD5. |
| Multi-valued | No |
| Required | No |
| Admin Action Required | None |
| Advanced Property | No |
| Read-only | No |
| Description | Specifies the fully-qualified name of the Java class that provides the SASL mechanism handler implementation. |
| Default Value | org.opends.server.extensions.DigestMD5SASLMechanismHandler |
| Allowed Values | A java class that implements or extends the class(es) : org.opends.server.api.SASLMechanismHandler |
| Multi-valued | No |
| Required | Yes |
| Admin Action Required | The Digest MD5 SASL Mechanism Handler must be disabled and re-enabled for changes to this setting to take effect |
| Advanced Property | Yes |
| Read-only | No |
